Abstract

The present study was conducted at Research Farm, College of Horticulture, Mandsaur, Madhya Pradesh during 2020-21. The experiment was laid out using Factorial RBD with IBA treatments (i.e. 0, 2000, 4000 and 6000 ppm) and different growing media (Soil, sand, Cocopeat, Soil + Sand + FYM, Soil + Sand + Vermicompost) under net house condition in poly bags. The different observations was recorded i.e. Shoot Parameters like shoot length, internodal length, number of buds per shoot, stem fresh weight, stem dry weight. Root Parameters like number of primary and secondary roots, root length, fresh weight of root, dry weight of root. Leaf Parameters like number of leaves per plant, fresh weight of leaf, dry weight of leaf, leaf area index (LAI). The hardwood cuttings when treated with IBA 6000 ppm and planted in Soil + Sand + Vermicompost had recorded significantly highest shoot and root growth in grapes. The best result was found for shoot parameter like shoot length (10.33 cm, 75 cm), number of nodes per shoot (7.71, 21.40), internodal length (3.21 cm,7.18 cm), number of buds per shoot (15.00, 32.55), stem diameter (19.34 mm, 29.32 mm) at 60 and 90 DAP, stem fresh weight (18.21g), stem dry weight (7.98 g) at 90 DAP. Root Parameters like number of primary (24.20, 38.59) and secondary roots (21.09, 32.43), root length (25.49 cm, 30.45 cm), root thickness (1.96 mm and 2.12 mm), whole root volume (22.36 cm2 and 29.47 cm2) at 60 and 90 DAP, fresh weight of root (6.93 g), dry weight of root (3.05g) at 90 DAP. Leaf Parameters like number of leaves per plant (13.86, 33.09) at 60 and 90 DAP, fresh weight of leaf (1.81 g), dry weight of leaf (0.86 g), leaf area (77.85 cm2), leaf area index (4.49), specific leaf weight (31.62 mg Dw.cm-2) at 90 DAP, while minimum days taken to emergence of 1st leaf (19.67 DAP) found in soil + sand + vermicompost with IBA @ 6000 ppm (M5G3).

Conclusion

The study concludes that production of guava plants in net house condition proved to be the best for rapid and cheapest method multiplication of grapes true-to-type plants. The application of growing media soil + sand + vermicompost 1:1:1 along with IBA 6000 ppm was observed significantly superior for growth (rooting and shooting characteristics) in hard wood cutting of grapes. The plants produced by this technique will be true-to-type. These plants will bear earlier than the seedlings. The unique characters of a variety can be preserved through this technique. The technique was developed in this study is simpler, rapid, less labour intensive and economical, as root promoting hormones are required for root initiation. It is useful as compared to conventional method of propagation (grafting/budding) of grapes because of higher success rate, independence of season and climate, small size of cuttings, use of juvenile shoot cuttings, disease free nature and production of large number of uniform true to mother type plants in a short period of time.
